BIlly from Vivid Racing will look after you. I tried a few guys and Billy was most helpful and reassuring which is what you want when you are buying from overseas.
I know i can be a bit of a ball breaker at times and not once did he make me feel like i was wasting his time.

Either LM or LM-R will looks great on e92 m3 for sure(one of best looking wheels)
i used to have LM on my E46 and Sti,yes...they are too many copy's and very hard to clean as well.....good choice on LM-R!!
